This invention relates to a device to sole and heel footwear, including worn footwear, and it relates to the rehabilitation and repair thereof.

Its principal object is to provide improved means for moulding a new sole and new heel of rubber or plastic material on and afiixing the same to an article of footwear whether that ar ticle be new-in which case the moulding process would take place during the course of the original manufacture of the article of footwearor whether that article be Worn, in which case the process would be one of rehabilitating or repairmg.

Another object is to provide an improved sole and heel moulding means susceptible of proper adjustment into marginal conformity with an article of footwear of the character described, adapted to shape and mould the shank thereof as well as the sole and heel member thereof.

Still another object is the provision of a device of the character described which may be used in conjunction with conventional shoe holding devices commonly employed by shoe repair men in small shoe repair stores.

A still further object is the provision of a device of the character described which consist of few, simple, inexpensive parts and which, when assembled, is light in weight and convenient to handle and use.

'Another object still is the provision of a device of the character described which is designed for cooperation with vulcanizing equipment of conventional types.

A preferred embodiment of the invention is shown in the accompanying drawings in which- Fig. 1 i a plan view of the device as a whole, said device being shown applied to a conventional article of footwear;

Fig. 2 is a transverse section of said device on the line 22 of Fig. 1;

Fig. 3 is a transverse section of said device on the line 3-3 of Fig. 1;

Fig. 4 is a fragmentary side View of the device;

Fig. 5 is a fragmentary detailed sectional view on the line 5-5 of Fig. 1;

Fig. 6 is a perspective view of the moulding band of said device, and;

Fig. 7 is a perspective view of a unitary sole, shank and heel member formed by said device.

Referring now to Fig. 6, it will be seen that the moulding member of the device comprises a unitary strip or band In of relatively flexible, relatively resilient material, such as spring metal. Band I0 is shown shaped to the marginal lines of conventional heel, shank and sole members 6 Claims. (CI. 18-34) of a conventional article of footwear. It is clear from the drawingsthat band I 0 i of substantially uniform thickness throughout but its width varies from a relatively ,wide heel portion which tapers gently at the shank portion to a relatively narrow sole portion. Band II] is provided at predetermined intervals with small holes H whose function will hereafter appear.

It will be noted that there is overlapping of the end portions of said band at the shank and that one end thereof curls outwardly at that point to form approximately two-thirds of a circle. The very tip end l2 of said circular portion I3 i bent over at right angles thereto.

Referring now to'Fig. 1, it becomes apparent that a ratchet mechanism M is disposed in the circular space formed by said circular portion i3 and thatsaid ratchetmechanism engages tip i2 thereof. Ratchet mechanism l4 comprises a r0- tatable wheel IE to which is aflixed a ratchet wheel l6, which ratchet wheel is engaged by a fixed pawl IT. A slot or notch in wheel accommodates the bent tip l2 of band I0. A square hole IS in said wheel I5 and ratchet wheel 16 accommodates a crank or key member which is not shown. It is clear that rotation of wheel i5 and ratchet wheel It in a counter clockwise direction as viewed in Fig. 1 causes a drawing together of band l0 and a consequent reduction of the space encompassed and defined by said band III. This will become clear as the specification proceeds.

Referring now to Fig. 1, it will be seen that whenthe band I 0 is placed in operative position upon conventional article of footwear 20, nail or tacks 2! inserted through holes H in said band afiix the band to the article of footwear and more particularly to the welt 22 and heel 23 portion thereof. Fig. 5 will show that a substantially L-shaped member 25 having a wedge shaped foot is mounted on each said nail or tack 2| tobrace and erectly support band I0 during the moulding operation. The wedge shaped foot is wedged by means of said nails 24 into the space between welt 22 and upper 25 adjacent the point where said welt, said upper and the inner sole 26 are respectively affixed to each other. At the inner end of. the heel section is a transverse band 2?, which extends at both ends to band 10. Between said transverse band and the sole portion proper is a shank core 39 which occupies the space corresponding to the space formed beneath the shank of a conventional shoewhen that shoe is placed upon a flat surface; The hank core comprises a pair of spaced longitudinally extending members 3| and 32 respectively which are mounted between a pair of spaced upper shank plates 33 and 33:11, respectively, and a lower shank plate 34.

Upper plates

33 and 33a have a pair of

side walls

35 and 36, respectively, with inwardly bent end portions 31 and 38, respectively, which correspond to the wedge shaped foot portions of bracing members 24 and perform the same function therewith. Lower shank P1317334 is provided with a rear Wall 39 which has a forwardly bent upper end portion 40. The forward end 4| of lower shank plate 34 is bent backward facing bent portion 40. It thus appears that the shank members 3| and 32 are held in place by upper and

lower plates

33 and 33a, and 34, respectively, and their

walls

35 and 36, and 39, respectively.

Referring now to Fig. 3, it will be noted that a transverse screw member 45 extends through apertures 46 and 4! inside

walls

35 and 36, respectively,

apertures

48 and 49 in the band member 10 and loose threaded apertures 56 and respectivelyin cores 3| and 32. It will be noted too that screw member 45 is rotatably fixed at its center portion in a bearing 52 which is mounted on lower plate 34. Said bearing permits of rotation of screw 45 on its own axis but prevents axial displacement of said screw relative to said bearing. .It will be noted also that screw 45 is provided on one side of bearing 52 with right screw threads and on the other side with left screw threads. Core members 3| and 32,.respectively, are provided with corresponding screw threads so that when screw 45 is caused to rotate on its axis, core portions 3| and 32 'will move in opposite directions either toward or away from one another.

Nuts 60 and 6|, respectively, are mounted on the opposite ends of screw 45 immediately

adjacent side walls

35 and 36, respectively. Nut 6| is provided with a square key receiving aperture 62. Screw 45 has affixed to the end opposite the end on which nut 6| is mounted aknurled knob 63.

Nuts 6!! and 6|, respectively, are used to tighten the contact between

walls

35 and 36 on the one hand and band It! on the other and band ill on the one hand and core members 3| and 32 on the other.

Referring again to Fig. 1, it will be seen that the foot portions 31 and 38, respectively, of walls 35 and '36 are provided with serrated edges which are intended when the band is drawn together as herein described, to prevent creeping. It will also be noted in 'Fig. 1 that upper plate 33 is provided with a slotted ear 65 which accommodates see Fig. 2-2. screw member 66 having eccentric wedge shaped .head 61 which performs the same function as the feet of braces 24 and the inwardly turned wedge members 31 and 38 of

walls

35 and 36, respectively. This slot arrangement permits of lateral movement of plate 33. Plate 3311 also has an ear 68 which is substantially as large as the cross-sectional dimensions of the ratchet mechanism I4. Fig. 2 will show that the ratchet mechanism is rotatably carried by said ear 68. The pawl I! of said ratchet mechanism which has hereinabove been described as a fixedly mounted pawl, is afiixed in the usual manner, as by pin 69 to said car 68.

It is not difiicult to understand .how the device above described may be used. It is mounted on the article of footwear by means of nails 2| as above described. Screw 45 and .nuts 60 and 6| are manipulated to adjust the positions of core members 3| and 32 with respect to each other and the degree of pressure contact between

walls

35 and 36 and band 16 and said core members 3| and 32. Ratchet mechanism I4 is now operated in the usual way thereby drawing the curled end of band I!) around it and urging said band into marginal conformity with the sole and heel members of said article of footwear. The device is now ready for use. A plastic material or rubber is poured into the mould and the operation continues fromthis oirrt on in the conventional manner. After the plastic material is set, the device is removed and the end product may be seen in Fig. '7 affixed, however, to the shoe. It is clear from Fig. 7 that what has been produced isa unitary member having a heel portion '10, a shank portion H integral therewith, and a sole portion 72 integral with said shank portion. The sole and heel portions of the unitary member shown in Fig. 7 are provided with. depressed portions (or raised portions) l3 which are formed therein in the usual manner by means of a suitable mould or otherwise.

' The device above described .is but a preferred embodiment of the invention and changes may be incorporated therein without departing from the basic principles thereof. These basic principles form the subject matter of the claims hereto appended.
